9. Storing Breast Milk
Storing Breast Milk in a Medela Cooler Bag
• Your Medela cooler bag requires one Medela frozen contoured ice pack. Up to four 5 oz.
bottles of breast milk will stay cool for up to 10 hours in a room temperature environment
inside your pump bag. Up to four 5oz bottles of breast milk will stay cool for up to 8 hours
in a room temperature environment, inside the cooler, stored outside of the pump bag.
• As soon as you are finished pumping, place the breast milk bottle or breast milk storage
bag in the cooler bag with the ice pack.
• Transfer breast milk bottles or breast milk storage bags to the refrigerator or freezer once
you are home.
